Your code is full of unfinished and unclosed stuff

<?php
$stoken = Util::getMD5GUID();
$gWeb->store("fb_state",$stoken);
$fbAppId = Config::getInstance()->get_value("470580912986218");
$host = "http://".$_SERVER["HTTP_HOST"];//--->fail to close properly
$fbCallback = $host."/callback/fb2.php" ;//---->fail to open properly
$fbDialogUrl = "https://www.facebook.com/dialog/oauth?client_id=".$fbAppId ;//---> total fckup
$fbDialogUrl .= "&redirect_uri=".urlencode($fbCallback)."&scope=em ail&state=".$stoken ;//--->$token begin with ( ". ) but not ending with ( ." )
 ?>

<?php
$stoken = Util::getMD5GUID();
$gWeb->store("fb_state",$stoken);
$fbAppId = Config::getInstance()->get_value("470580912986218");
$host = "http://".$_SERVER["HTTP_HOST"]."";
$fbCallback = "".$host."/callback/fb2.php" ;
$fbDialogUrl = "https://www.facebook.com/dialog/oauth?client_id=".$fbAppId."";
$fbDialogUrl .= "&redirect_uri=".urlencode($fbCallback)."&scope=em ail&state=".$stoken."";
 ?>

Facebook has a PHP sdk that helps you with heavy lifting. Use it.
